To all whom it may concern:

Be it known that I, GEORGE H. WILLIAM- SON, a citizen of the UnitedStates, residing at Jersey City, in the county of Hudson and State ofNew Jersey, have invented new and useful Improvements in Toys, of whichthe following is a specification.

This invention relates to toys and has for its principal object theprovision of a device of this character which will be instructive,educational and amusing; one which may be readily converted from aportable wheeled structure of one design to other portable structures:of many designs, each of a mechanical formation which will permit of itssustaining the weight of a child and capable of being propelled over thesurface of the ground.

With the above and other objects in view which will appear as the natureof the invention is better understood, the same consists in the improvedconstruction and novel arrangements of parts which will hereinafter befully described and particularly pointed out in the claims.

In the accompanying drawings, has been illustrated, a single andpreferred form of the invention, it being, however, understood, that nolimitations are necessarily made to the precise structural detailstherein exhibited, but that changes, alterations and modificationswithin the scope of the claims may be resorted to when desired.

In carrying the invention into practice, use is made of a number ofstock mechanical elements all or a part of which constituting one of themany portable structures to be hereinafter specifically referred to.These elements are simple in design and are adapted to be assembled withone another for the completion of the object to be formed withoutrequiring any extended skill of mechanics. Therefore, the device may beset up and knocked down and converted from a structure of one design toa structure of a totally different design by the inexperienced mind of achild. The device nevertheless, contains many educational features inthat the various elements constituting the same may be technicallycatalogued and the trainin afforded a child in setting up the many dierent objects is quite material and beneficial, saying nothing-0f theenjoyment and pleasure which may be had'through the use of the differentforms of structures as they are set up by the child. I have as far as ispracticable, used a set of mechanical elements in which almost the sameelements will be employed when changing the device from a structure ofone type to a structure of a different type.

In the form shown 1n Fig. 1, the same being a two wheeled cart, use ismade of a platform 1, two diverging reach bars 2-2, an axle 3, havingwheels 4.--4, and a pole 5. At the front end, where the reach bars cometogether, a small clip 6, is used which is as shown, said pole isextendedthrough the eye 8, of the clip and the rear end which isprovided with spaced plates 9-9, is arranged over a removable block l0,under the reach bars and a bolt 11, is then passed through the platform1, and through the block 10, and a small metal cross piece 12, whichextends over the plates 9-9. In ad bolted at 7 beneath the said reachbars and Yo aK.

Specification of Letters Patent.

Patented To all whom it may concern:

Be it known that we, OTTO NINKLER, a sub ect of the King of Prussia,residing at Copenick, Germany, and RUooLr Uurnn, a,

subject of the King of Prussia, residing at N ieder-Schoneweide,Germany, have invented certain new and useful Improvements inValve-Gears. for Internal-Combustion Englnes, of which the following isa specification.

This invention relates to internal combustion engines, and its object isto utilize the pressure of the expanding gases in the cylinder to assistin the movements of the valve gear. The operation of opening the outletpassage in such engines must be effected very rapidly, necessitatingextreme acceleration in the movement of the valve and its gearing. Bycausing the pressure of the exploding charge to act upon this valve, themechanism Which operates it is assisted and greater promptness ofoperation is secured. To this end we use an annular valve located insidethe cylinder and actuated by a rod or stem passing out through astuffing box in the head of the cylinder. The inlet and outlet ports orpassages are both controlled by this one valve, the arrangement beingsuch that the outlet passage is opened when the valve stem movesoutwardly from the interior of the cylinder and the inlet port when thevalve moves inwardly.

The accompanying drawing is a diagrammatic section of a cylinder of aninternal combustion engine, showing our improved construction of thevalve.

The cylinder 1 has an-outlet or exhaust port 2 located below the planeof the inlet or fuel admission port 3. The annular slide valve 4controls both ports, and is actuated by the stem 5 which passes outthrough an opening in the head 6 of the cylinder. In practice, thisopening is of course provided with a suitable stutfi'ng box or packing.When the charge has been: fired, the pressure in the combustion chamberbetween the head 6 and the piston 7 acts upon the cross sectional areaof the stem 5 and tends to lift the valve thereby assisting the valvemechanism in effecting a quick uncovering of the outlet port 2.Moreover, when the suction stroke of the piston occurs, the atmosphericpressure on the outer end of the stem aids the valve mechanism inopening the inlet port. To state the matter in anbustion engine, of avalve locat l ins in rt 3 and later in open)- opening the fuel po ingthe exhaust port With this arrangement, therefore, the movements of thevalve in each direction are ed'oeted in part positively by the valvemechanism and in part automatiealtv b the unbalanced lluid. pressures onthe valve and its stein.

\Ve have not illustrated the means for moving the valve since ablemechanism for the purpose in ployed and further because it seemsunneeessary to an understanding of the invention. 'T() e able theinvention be more readily understood. the moving and st. ary parts havebeen separated by relatively fill large clearances. In practice thesemake, of course, a good working in accordance with the provisions ofpatent statutes. we have described the principle of operation of ourinvention, together with the apparatus which we now consider torepresent the best embodiment thereof; but we desire to have it underapparaus shown is only illustr" l the invention can lie carried means.

Whatwe claim as no '7 and desire to cure by Letters Patent oi the UnitedStates, is
